Fertility-sparing treatment of endometrial cancer precursors among young women: a reproductive point of view

BACKGROUND: Early-stage endometrial cancer and complex atypical hyperplasia are treated with hysterectomy and bilateral salpin-go-oophorectomy. An emerging issue among younger women affected is the possibility of a fertility-sparing treatment with progestative therapy and close follow-up. AIM: To assess the possibility of conceiving after a diagnosis of atypical endometrial hyperplasia among women younger than 40 years old, in term of delaying definitive treatment and achieving pregnancy MATERIALS AND METHODS: 15 women younger than 40 years old with complex CAH or early carcinoma of the endometrium and a wish to preserve fertility. Progestins were administered orally for at least a 12 weeks period. Endometrial biopsies were used at follow-up. RESULTS: In 11 women, a complete pathological remission of the disease was observed. 4 pregnancies were attained in 4 women. 3 showed progression and underwent definitive surgery at 18 months. 1 showed no response at 24 months and 3 cycles and was counseled to receive a hysterectomy. CONCLUSIONS: A conservative approach in patients younger than 40 years appears a valid option, and a progestative therapy trial should be attempted whether a valid consensus is attained. Considering the risk to find AEH at biopsies and eventually a carcinoma at hysterectomy (25% of cases) a careful management is strictly required.
